I finally found a document with my paternal great grandmother's name and it's hard to read. Can anyone help?
Thanks!--

Raylene,

Might be RAUCHLESE.

I think it's Rauchlose

I vote for Rauchlese. Blowing up the image, it's clearly an "e" after the "l". There's no serif sticking up from the blob that is the last letter, so I don't think it's an "s"

I'd look at the rest of the document not shown in the snip provided.  The mystery is the final letter.  I'd hope that same typewriter key was needed elsewhere on the document and can be deduced from context.
